Zero calibration
Zero Calibration is to calibrate the zero position of the scale platform.There are two
ways for zero calibration: automatic acquisition and manual input.When the new
equipment or weighing structure is adjusted, the "automatic acquisition" method must
be used for zero calibration.
automatic acquisition
：
Calibration success conditions: the metering bucket emptied, balance platform
stable.
After empty the scale, controller displays the current millivolt. Press
[Calibration Zero]
to calibrate the current state as zero state.
manual input
：
Manually input zero corresponding to millivolt value, click
[Cal ZERO By
Valtage]
, input the recorded zero voltage value in the pop frame to calibrate as zero.
The voltage value is the data recorded when the weight is calibrated. The recorded
value is used for manual input.
Weight calibration
The function of weight calibration is to use the weight calibration method in the
field.Here are the steps:
Step 1: According to the demand to choose units, decimal point, Minimum
division and other weighing parameters
Step 2: To Calibration Zero, refer to the calibration steps of the Calibration Zero.
Step 3: Put the weights on the weighing table, and when the weighing table is
stable, click
[Calibration Weight],
input the weight of the weights in the bullet frame,
and click "
Enter
" to complete the calibration of the weights.
